{"title":"Integrating Micro-lesson Metadata in ID3V2 of MP3","authors":"Kaushalya Yatigammana, G. Wijayarathna","doi":"10.1109/fiti54902.2021.9833061","DOIUrl":"https://doi.org/10.1109/fiti54902.2021.9833061","url":null,"abstract":"Online teaching emerged as the only feasible mode of teaching and learning during the pandemic. This mode of learning demands Internet connection to every household and strong signal coverage. Lack of connecting devices and sharing of a single device among siblings are common problems. Staring at small screens of smartphones and lack of physical activity due to tight online class schedules create health issues too. Delivering pre-recorded multimedia lessons (micro contents with 15 minutes duration) followed by discussions with students using a virtual meeting platform will lessen these problems. Breaking down a single lesson into multiple short sub-lessons needs a robust sequencing mechanism to provide the necessary guidance for the students to follow micro lessons in a desirable order. This sequence information should be available with lessons themselves. That is, metadata related to navigation or sequencing should be kept with the lesson itself. The IEEE standard on Learning Object Metadata does not provide such sequencing metadata, while SCORM does. Metadata is stored in separate XML files in SCORM, and the lesson and the metadata files should be zipped to a package. This needs Learning Management Systems (LMSs) to handle metadata and lesson contents separately. However, most educators do not use LMSs and do not have enough technical expertise to create and manage these metadata. MP3 is the best file format for minimizing file sizes while retaining good audio quality. The ID3v2 tag area carries audio metadata with the MP3 file itself. MP3 with ID3v2 tagging has already been used in NeLCon Studio to deliver digital lessons to students. NeLCon studio provides an easy way to embed metadata into ID3v2 area and attach them into MP3 itself. This paper proposes the required lesson metadata and re-designed the ID3v2 tag area to embed this information. This mechanism has several advantages like keeping metadata and micro contents together, providing sequencing metadata of micro contents for sharing them among multiple courses, encouraging even non-technical educators to create micro contents which can reduce the staring time at small screens for a longer period by students, increasing their physical activities, and delivering and using micro contents with Internet connection having poor signal coverages or in coverage holes. Students will be guided to follow the micro contents in the order the educators decided to achieve the lesson outcomes. This work lays the foundation for MP3 based mobile and social media learning platforms.","PeriodicalId":201458,"journal":{"name":"2021 From Innovation To Impact (FITI)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132162738","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though social innovation research has received increased attention from researchers in the last decade, the concept is not free from conceptual ambiguities. Thus, the overarching objective of this study is to form a typology for SI. A qualitative research paradigm is adopted in this study based on the nature of the study phenomena. The study adopted the maximum variation sampling strategy to derive the study sample and interviews were conducted with 24 Sri Lankan social enterprises. The data were thematically analyzed, and theoretically positioned the typology based on two building blocks: a) efficiency and b) effectiveness of social enterprises. Subsequently, the paper explored three types of efficiency-based SIs, namely, a) market efficiency-based SIs, b) organizational efficiency-based SIs, and, c) mission efficiency-based SIs. The three types of effectiveness-based SIs are a) market effectiveness-based SIs, b) organizational effectiveness-based SIs, and, c) mission effectiveness-based SIs. By doing so, the study provides significant implications for SI theory, practice, and policymaking.","PeriodicalId":201458,"journal":{"name":"2021 From Innovation To Impact (FITI)","volume":"48 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126926995","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because of its widespread use, it is one of the most ubiquitous contaminants in the aquatic environment resulting in adverse impacts on the quality of aquatic life. We investigated the presence of BPA in the surface water collected from the Bolgoda lake during the dry and wet periods. The average concentrations of BPA detected in the samples with receipt of BPA from the Karadiyana solid waste open dump were in the range of 3.3–29.2 and 1.0–1.2 µg/L in the wet and dry periods, respectively. The concentrations of BPA detected in the Bolgoda lake in the wet season were significantly different from that of the upstream sample with no receipt of BPA from the open dump (p < 0.05), suggesting substantial evidence of migration of BPA from the dumpsite. Moreover, BPA levels of the same locations in the dry season were not significantly different (p > 0.05), indicating no signs of leachate rich in BPA being mixed with the Bolgoda lake. The correlation results indicated that both pH and temperature follow a negative relationship with BPA. Our acute ecological risk assessment findings indicated high acute risk in the wet period and medium acute risk in the dry period for Mozambique tilapia (Oreochromis mossambicus) and grass carp (Ctenopharyngodon idella).","PeriodicalId":201458,"journal":{"name":"2021 From Innovation To Impact (FITI)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129615446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, a reliable mechanism to prevent and control the obesity levels is vital. This paper aims to present an initiative of the process for developing an obesity dietary control system. The research method included a literature survey which covers reviewing sources such as journal articles, conference papers, and books. Resulting from the review, some information on the weakness of the existing system was found. Resulting from the previous studies, it was found that managing the lifestyle of obese people by controlling their daily diet to get the ideal body gave uncertain results. This new initiative to develop such systems may be based on a machine learning technique, which could classify and predict the nutrients consumed by obese people. The significance of this study may lead many experts and researchers, who are interested, to explore more solutions that help to combat the obesity phenomenon. As for the future study, we will emphasize the development of a software tool which can provide guidelines with an appropriate technique, to support obese people in controlling their daily diet and activities.","PeriodicalId":201458,"journal":{"name":"2021 From Innovation To Impact (FITI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115280455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, the primary mode of higher education has dramatically shifted to online learning and student evaluations are done through online exams. Although online exams deliver strong contributions during this pandemic period, the sudden adoption of online exams inevitably caused additional impacts that have become a timely necessity that should be researched and studied. This study explores students’ priorities in online exams, preferred evaluation methods to attend online, and possible dishonest behavior in online exams from the students’ perspective. Some key findings are related to the most common behaviors of students that appear in online learning. Furthermore, challenges which the students face in online exams and online learning are investigated. Findings are based on 512 responses collected through an online survey from the students at a state university in Sri Lanka. The study discloses that the students have come up with a positive perception of attending online exams to fulfill the evaluation requirements during this global pandemic. Homework assignments, take-home / open-book examinations, and multiple-choice questions are preferred online evaluation methods among the students. However, academic dishonesty has become a leading issue that must be eliminated to ensure academic integrity in online exams.","PeriodicalId":201458,"journal":{"name":"2021 From Innovation To Impact (FITI)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124657460","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prepared laminated rubber sheet is pasted on the palm area of the glove, which is made of Kevlar fabric. The low adhesion causes the laminated rubber sheet to separate from the fabric. The main objective of this research is improving the adhesion ability of laminated rubber glove in the manufacturing process. This study consisted of three main experiments (I, II and III). Preliminary experiments were done based on a common formula of adhesive and the existing process line before applying the modifications in each experiment. Experiment I was carried out to find out the accurate volume of secondary solvent, called SBP, to give the best adhesion, accurate viscosity value, and the Total Solid Content (TSC) value during the highest adhesion level of the adhesive blend which is used to paste the rubber sheet to the fabric. Experiment II was conducted to modify the existing process line by changing the conditions of critical process steps identified by preliminary tests, which are smoothing, maturing and curing/vulcanization in an autoclave to increase the adhesion ability of laminated rubber glove. Experiment III was done to change the adhesive formula by changing the tackifier (wood resin) amount which is the most influential ingredient to enhance the adhesion ability of adhesive under most appropriate combinations of the curing temperature with curing time, based on the results of experiment II. Adhesion tests were done by using Tensile Tester for all completed replicates prepared under each sample of experiments I, II and III, and data were analyzed by using MINITAB 16 statistical software. According to the end result obtained through these experiments, the new adhesive blend should consist of the adhesive compound with primary solvent to SBP in the ratio 1:2, with the addition of 14% of wood resin as tackifier, based on the total for the adhesive formula, to improve the adhesion value, and the manufacturing process line should consist of two smoothing turns, a 24 hour maturing period as resting time before curing, and a curing temperature of 1200Ϲ with 90 minutes curing time in an autoclave to improve the adhesion ability of the laminated rubber glove.","PeriodicalId":201458,"journal":{"name":"2021 From Innovation To Impact (FITI)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128190395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
